Abstract

Aim of this paper is to present a self-testable FIFO memory macrocell, which can be embedded into larger devices. A dual port RAM-type FIFO has been designed. A new test procedure for the macrocell has been defined aiming at detecting all possible faults in the control logic and the RAM cell. Given such a test procedure the appropriate Built-In Self Test architecture has been defined, independently of the memory size. Fault coverage and area overhead for the proposed solution are presented.
